উৎপাদক প্ৰকাশ কৰা:-x²-13x=30

Answer 1

x²-13x=30

x²-13-30=0

x²-2x+15x-30=0

x(x-2)+15(x-2)=0

(x-2)(x+15)=0

x=2, x= -15

Answer 2

Answer:

${x}^{2} - 13x = 30$

${x}^{2} - 13x - 30 = 0$

${x}^{2} - (15 - 2)x - 30 = 0$

${x}^{2} - 15x + 2x - 30 = 0$

$x(x - 15) + 2(x - 15) = 0$

$(x - 15)(x + 2) = 0$

$(x - 15) = 0 \: \: and \: \: (x + 2) = 0$

$x = 15 \: \: and \: \: x = 2$

Ans. (x - 15)(x + 2) ; x = 15 and 2

Hope it helps.
